Description

The adjustment axle of turbosupercharger is arranged
The present invention relates to adjustment axle arrangement according to a kind of VTG turbosupercharger or the wastegate turbosupercharger of claim 1.
" VTG turbosupercharger " speech is meant a kind of turbosupercharger with variable turbine geometry (VTG), and it requires to have one and adjusts axle arrangement.In the wastegate turbosupercharger, this turbine bypass is to control by a valve, and this valve is to move by adjusting axle.
In the adjustment axle of known VTG turbosupercharger is arranged, depend on the exhaust positive pressure that is applied, the faulty problem of sealing effect may take place in the clearance seal in the zone between this adjustment axle and lining, and this may cause outside discharging waste gas of this turbosupercharger and smog.
The known Sealing that passes through a kind of improvement of a piston ring of center installation in lining among the W02004/063535 A1, its sealing effect and this clearance seal effect combine like this.
Yet, this arrangement has an important shortcoming, in bush hole, be used to assemble the desired formula inclined-plane that slips into of this piston ring and reduced effective clearance seal length significantly, because, in a kind of bush structure and the assembling of symmetry that is not transversal orientation, slip into of another end face of lining that the formula inclined-plane also just necessitates easily.
Therefore the object of the present invention is to provide the adjustment axle arrangement of a kind of VTG or wastegate turbosupercharger, this arrangement at first constitutes a combination of clearance seal and piston ring seal, so that reduce its outside exhaust gas discharged and smog significantly, and secondly also on identical liner sleeve length, make a kind of improved sealing effect become possibility.
Feature by claim 1 has realized this target.Each dependent claims relates to a plurality of favourable improvement of the present invention.
According to the present invention, between this adjustment axle and lining, provide a static seals, even described confidential paper can not prevent fully, at least also can reduce this turbosupercharger significantly by outside exhaust gas discharged of lining and smog.
The sealing part preferably is designed to a piston ring type.
In an especially preferred embodiment, the sealing part is arranged in the groove of this adjustment axle main body between a standing part and free end.
This main body is a stepped design, causes two cylindrical parts with various outer diameter.Therefore and then cause two parts with different cylindrical inner diameter sizes the in-profile that is wrapped in the lining of this main body similarly is complementary stepped design.Transition portion between the zone can be designed to one and slip into the formula inclined-plane and be used to assemble this piston ring, has all kept a long as far as possible effective seal clearance like this at two ends.In this case, the annular space that produces owing to this transition part branch between lining and adjustment axle can become a particle collecting area.Because the accumulation of particle in collecting area just can be avoided the accumulation in the sealing gap, and the accumulation of the particle in seal clearance may cause the slow of this adjustment axle.The external diameter of this lining need not be stepped design.It can be constant on whole liner sleeve length also.The cascade external diameter of lining has additional advantage, has promptly prevented the mistake assembling of lateral reversal.
To provide other details of the present invention, advantage and feature below with reference to description of drawings to the explanation of two illustrative embodiments, comprise in the accompanying drawing:
Fig. 1 illustrates a known schematic partial cross-sectional view of adjusting the axle arrangement;
Fig. 2 illustrates the schematic representation of arranging (VTG) with Fig. 1 accordingly according to this adjustment axle in first embodiment of the present invention; And
Fig. 3 illustrates the schematic representation of arranging (wastegate) with Fig. 1 accordingly according to this adjustment axle in second embodiment of the present invention.
Fig. 1 illustrates the known adjustment axle of a VTG turbosupercharger and arranges 1.Itself does not show more details in the drawings this VTG turbosupercharger, because this can comprise that this is as a known conventional configurations.
This adjustment axle arranges 1 to have one to adjust axle 2, and it comprises a standing part 3 and a free end 8.In addition, Fig. 1 shows the main body 6 of the external diameter of this standing part 3 and free end 8 less than this adjustment axle 2, and described main body 6 is arranged between this standing part 3 and the free end 8.Three all in this example parts all have columniform exterior contour.
This adjustment axle 2 is connected with a bar 4 by standing part 3.
In addition, this adjustment axle arranges 1 a lining 5 is arranged, and it is arranged on the base main body 6 of adjusting axle.
At last, provide a Sealing 7, it is arranged on the element body 6 between lining 5 and the adjustment axle 2.For this purpose, this element body 6 has an annular groove and sealing part to be preferably designed to be arranged in a piston ring in the groove 9.So just can and adjust between the axle 2 or obtain a sealing that can limit smog emission or exhaust gas leakage significantly on its main body 6 at lining 5 to the outside.
In as shown in Figure 1 adjustment axle was arranged, the base main body 6 of this adjustments spools 2 was continuous cylindrical or smooth design fully, and all can be clear that at two end faces of lining and to slip into the formula inclined-plane.
Compare therewith, in first embodiment as shown in Figure 2 that this adjustment axle according to the present invention is arranged, be equipped with a stepped basic main body 6, cause two cylindrical parts 10 and 11 thus with various outer diameter.In the illustrated embodiment, the external diameter of part 10 is greater than part 11.
Therefore, at this internal diameter of adjusting this lining 5 in the zone of part 10 of axle 2 greater than zone around part 11.
In this embodiment according to the present invention, Sealing 7 also is arranged in the groove of this basis main body 6.Therefore, relevant all corresponding features can be with reference to the explanation of figure 1.
Fig. 2 also demonstrates, and this lining 5 has two parts 12 and 13 equally, and the part 12 that has than large diameter is holding the part 10 of adjusting axle 2, and part 13 is holding the part 11 that has less external diameter on the adjustment axle 2.In addition, the part 12 of this lining 13 has the external diameter littler than the part 13 of lining 5, and extra disclosure can be referring to the indicative icon of Fig. 2.
Fig. 3 is depicted as second embodiment that a wastegate turbosupercharger provides.Because it is still corresponding with Fig. 2 to adjust the design of axle, can be with reference to above explanation.
